Native Bee Pollination

According to the Xerces Society for Invertebrate Conservation, there are over 4000 species of native bees in the U.S. alone. Bees are the most predominant pollinators of flowering plants in nature, thus contributing a vital service to the ecosystem. Because of this important role, bees are referred to as “keystone organisms”.

Some native bees have names that reflect how they build nests—leafcutter bees, mason bees, miner bees, carpenter bees, digger bees, etc. Others are named for their behavior, which include bumble bees, sweat bees, and cuckoo bees. Finally there are some bees that are named for the types of plants they pollinate such as squash, sunflower and blueberry bees.

If honey bees are in short supply, the pollination needs of many crops can often be filled by native bees. Research has shown that native bees can be major pollinators of agricultural crops and sometimes do the job more efficiently. For instance, the blue orchard bee is a primary pollinator of cultivated apples. Another important crop pollinator is the western bumble bee, which has been used to pollinate cranberries, avocadoes, and blueberries. Native squash bees are major pollinators of cultivated squashes. Some native bees are even commercially managed like honey bees to provide pollination services.
